Phylogenetic relationships within the P. insularum/canaliculata clade using Pomacea paludosa as the outgroup. Analyses were based on combined 12S-16S (~1,900 bp) and COI (~658 bp) datasets including native range and introduced apple snail samples. Bayesian posterior probabilities are listed above branches, bootstrap proportions below. Taxon labels of specimens collected from outside the continental U.S. are shown in grey font. Relative branch lengths are illustrated in the phylogram shown in the inset. Abbreviations are: P.ins = P.insularum; P.can = P.canaliculata; P.pal = P.paludosa; FL= Florida; GA = Georgia; TX = Texas; BRA = Brazil; ARG = Argentina; HI = Hawaii; AZ = Arizona; CA = California.
